So, I have a slight problem with hair algae. It isn’t really causing any issues (as far as I can tell), but it is a bit of an eyesore. Because of this, I went looking for creatures that would eat it. According to this website (), ghost shrimp will eat the hair algae. My mother has some hair algae and some ghost shrimp, the latter doing nothing about the former. Later in the article, it mentions that the shrimp do not like being off of the substrate and would thus not eat any floating stuff, which is perhaps her problem. Have ghost shrimp done anything for your hair algae? And do you have any tips for getting the hair algae down from the surface? Thank you for any help!
